l j Y VALVE STRUCTURE.

Application filed February 27, 1924, Serial No. 695,518.

To all whom t may concern:

Be it known that I, ARTHUR W. BEAUR- LINE, a citizen of the United States, resident of St. Paul, county of Ramsey, and State of Minnesota, have invented certain new and useful Improvements in Valve Structures, of which the following is a specification.

This invention relates to new and useful improvements in valve structures and more particularly relates to such valve structures which are adapted to direct the flow of a liquid through and from the structure. In other words, this valve structure is not primarily useful for shutting olf the flow of a fluid but is primarily useful in directing the flow of the fluid inr such manner that there will be offered substantialy a minimum of resistance to the directed fluid-flow through the structure. In addition to such minimizing of resistance to flow, the valve structure has the added advantage of com pactness and its construction is such that it Vmay be integrally formed from a single casting. K

The particular form of valve structure here shown is one operable to direct the exhaust from an internal combustion engine for the purpose of employing the hot exhaust gases to heat the interior of a bus, automobile or similar vehicle driven by the engine. This novel valve structure is adapted to receive the hot exhaust gases from such an engine and to direct them throughy a main exhaust passage to the usual muffler or to direct the gases throughl an auxiliary passage to a radiator or heating units. During warm weather the `exhaust gases are directed to the muffler while in cold weather they are directed through thel radiating element. This unitary valve structure has an intake passage, an exhaust passage and one or more auxiliary passages through which the gases may be selectively directed through f operation of a suitable valve or gate.'

The object therefore of this invention is to provide an improved valve structure.

A more specific object of this invention is to provide an inexpensive and compact valve structure by which the directional flow of a fluid may be controlled with minimized resistance.

Other objects of the invention will ap,- pear from the following description and the accompanying drawings and will .he pointed out in the annexed claims.-

In the drawings, there has been disclosed a structure designed to carry out the various objects of the invention but it is to be understood that the invention is not conlined to the exact features shown as various changes may be made within the scope of the claims which follow.'

In the drawings: f

Figure l is a vertical sectional view on the line 1-1 of Figure 3, showing the valve in normal position, the gate `therein being positioned to allow the exhaust gases to pass directly through the' valve to the `muflier in the usual manner;

Figure 2 is a view in side elevation showing the preferred means for actuating the valve; and

Figure 8 is a top viewfof the valve showing the openings on the sides thereof adapted to be connected to the heating elements.

In the selected embodiment of the invention herey shown, there is illustrated a valve structure comprising a novel casing 4t which may be formed of an, integral compact casting. This casing hasv an intake passage 5 at one end thereof adapted to be connected to one end of the usual exhaust pipe 6 of the engine'preferably by such means as the usual nut 7 and compression gasket S. A main exhaust or 4discharge passage 9 is provided at the other end of the casing substantially in horizontal alinement with the passage 5 and normally ism communication therewith, as shown in Figure l. The main passage 9, in like manner, is connected to a section ll-of the exhaust pipe by means of A feature of this invention resides in the provision of means whereby the exhaust gases, expelled from the engine, may be `directed from the usual exhaust pipe to suitable heating elements mounted in the vehicle for heating purposes. Such means consists in the provision of opposed auxiliary passages let in the valve casing 4:.k These passages are adapted to be in communication with the intake passage 5 andare provided with suitable threads 15 by means of which they may be connected to pipes klleading t0 the heating elements (not shown).

A valve `or gate 1G is pivotallyl mounted Within the casing et and functions to direct the f'loiv of exhaust gases from the pipe G through the casingto the main exhaust passage 9 at the end of the casing or7 outivardiy through the opposed auxiliary passages 11i to the heating elements. The gate 16Vis mounted in bearings 17 and 18, preferably formed in a pair of plates 19 and 21 secured tor the sides of the casing by suitable means .such as screws 22.

Means are provided Jtor actuating the gate 16 which vpreferably `consist in mounting an arm 23 on the pivotal portion 2st of the gate. in operating rod 25 is terminally connected to the depending end of the arm Q3 and leads to a place Where it may conveniently berrached by the driver for the purpose ot operating the gate. A tension spring 2G`is preferably mounted yieldably to retainthe gatein either of its positions because the longitudinal axis et the spring passes through the pivotal axis ot the gate as the gate is moved from one position to another. rlhis spring hasv one end connected to the central portion ot the arm 23 and? its other end is connected to the casing by means vof a stud 2T secured thereto.

The casing et `may conveniently be supported by means ot alug QS, provided on the valve casing. This lug is apertured and adapted to cooperate with a stationary inember 2S) anda bolt 31 to support the valve structure and theretoi'ethe exhaust pipe.

The auxiliary exhaust passages 414e oppositely extend 'trointhe intake passage and in this preferred embodiment, these auxiliary passages oppositely extend in vaxial alinenient ivith each other and turtherpthe corresponding Walls oi each passage 14 meet within the intake passage 5 substantially in its median plane in order to-assure'an equal distribution of the intakenv gases toithe tivo auxiliary passages 1st. i rlhe juncture ot these two Walls is in a pointed edge 32 Which functions as a detl'ecting means so thatlessenedresistance to flow is thereby offered While the correspondingouter Walls of the two :auxiliary passages arcuately extend Jfrom this edge 32 and such sweeping curves minimize the resistance to flow caused' by thc change fot direction. "It may also be noted that it is preferable to form` the auxiliary passages so that their longitudinal axes asthey arcuately extend into the -intake passage meet each-other substantially in the similar axis of the intake passage. rl`hev main passage 9 is upwardly offset to pass around the juncture of the auxiliary passages With the intake passage.

In the use of this particular embodiment offthe valve structure,`the casing may be conveniently mounted by the lug 28 so that the pipeconnections from the engine and to the nnitiier and radiating units may be made while the operatingrodA 25 may project upwardly in position conveniently accessible to the operator ot the vehicle. lVhen the rod 25 is in its full line position shown in Figure 2, the exhaust gases from the engine are passed through the main passage 9 as shown by the arrows in Figure 1 and, ivhen therod is, moved to the dotted line position shoivn in Figure 2, the valve or gate 1G Willi be moved to its dotted line position in Figure 1 and the heated gases will be directed to the auxiliary passages 141.
